So I had to download the game as usual however I didn't do this step correctly. I had to look into the game file on my Mac and ran the updater. This helped and the message wasn't showing anymore after following the steps on downloading the game.
In order to use the updater you need to open a terminal in the game directory (or open a terminal anywhere and run `cd <gamedir>` - replacing the <gamedir> with the correct path on you system).
2) Run: `chmod +x updater`
3) Note that this is one time operation, you don't need to do it every time you want to update the game.
4) Now you can update your game using: `./updater`
- In case you're using ARM base Mac OS (M1) then use `updater-arm` instead in the commands above
